Dust Suction Device with Nested Storage Using Supporting Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust suction devices face challenges in storage due to structural instability and incomplete accommodation of components, leading to exposure and increased weight on the quick-installation structure, which can cause collisions and hinder transportation.
Innovation Solution
A dust suction device design featuring a supporting ring and dust suction assembly with connectors and airtight elements, allowing the assembly to be completely stored within the dust collection barrel by utilizing a supporting ring as a base for stacking and accommodating the assembly inside, reducing volume and facilitating transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the head housing is suspended on the opening of the dust collection barrel using the quick-installation structure, then the dust suction device can be stored in a compact configuration, but the quick-installation structure bears considerable weight and may cause structural instability
Solution Approach 1:
The invention divides the storage support function into two separate components: the quick-installation structure (for connection and detachment) and the supporting ring (for weight bearing and stability). This segmentation allows the quick-installation structure to remain lightweight while the supporting ring provides the necessary structural support during storage.
Solution Approach 2:
The supporting ring acts as an intermediary component between the head housing and the dust collection barrel during storage. It receives the weight of the head housing and distributes it to the dust collection barrel, preventing the quick-installation structure from bearing the full weight.
2Ease of operation
If the head housing is suspended on the opening of the dust collection barrel, then storage is enabled, but components on the head housing may still expose outside the dust collection barrel, preventing complete accommodation
Solution Approach 1:
The supporting ring is designed to fit within the dust collection barrel opening while providing a platform for the head housing. This nested configuration allows the head housing to be completely contained within the dust collection barrel during storage, with all components properly accommodated.
3Volume of moving object
If the quick-installation structure bears the weight of the head housing and motor, then storage configuration is achieved, but the structure may cause the head housing to collide with the filter element in the dust collection barrel
Solution Approach 1:
By separating the support function from the connection function, the invention eliminates the risk of collision between the head housing and filter element. The supporting ring provides stable weight bearing without the mechanical constraints that could cause collision in the quick-installation structure.

AI summary
A dust suction device includes a dust collection barrel, a supporting ring and a dust suction assembly, the barrel includes an inner space, an assembling opening communicating with the space, and at least two connectors disposed on the barrel, the opening has an opening diameter. The ring is placed at the opening, and has a ring outer diameter larger than the opening diameter, and a ring inner diameter. The assembly includes a shell and at least two connecting structures formed on an outer surface of the shell and used to restrict the assembly from separating from the barrel, the shell has at least one shell outer diameter smaller than the opening diameter, but larger than the ring inner diameter, the assembly has a use state by using the ring as a base and stacked above the barrel, and a storage state of being placed in the space.
